Research ArticleOpen accessIn the abstractOptical Characterization of Lead-Bismuth Phosphate GlassesH. A.A. Sidek, M. Hamezan, A. W. Zaidan et al.Systematic series of lead-bismuth phosphate glasses, where PbO, Bi2O3 and P2O5 content change for every series based on their weight percentage have been prepared. The optical properties were measured and their amorphous nature was confirmed by X-ray diffraction technique. Both experiments were conducted at room temperature. The fundamental absorption edge for all the glasses was analyzed. The values of refractive … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 7,436 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectrochemical Characteristics of Some Purpurins in Aqueous and Nonaqueous SolutionsFarouk A. Rashwan, Hossnia S. Mohran, Ahmed A. El-SamahyThe Electrochemical Impedance Technique (EIS) and the Cyclic Voltammetric method (CV) were used to investigate the behavior of purpurin (P), Anthrapurpurin (AP) and Benzopurpurin (BP) in aqueous and in N, N-dimethylformamide (DMF) media. In the CV experiments, both the radical and the dianion of these substances were assumed to form of limited stability due to chemical protonation. In case of … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 6,744 accessesView PDFCite
Research ArticleOpen accessIn the abstractScholastic Achievement of Higher Secondary Students in Science StreamZebun N. KhanThe present study was conducted on 400 students (200 boys and 200 Girls) selected from senior secondary school of A.M.U., Aligarh-India, to establish the prognostic value of different measures of cognition, personality and demographic variables for success at higher secondary level in science stream. The scores obtained on different variables were factor-analyzed to get a smaller number of meaningful variables … …Journal of Social Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 7,315 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Analysis and Design of the Enhanced Firewall for Intranet SecurityU. K. Singh, A. K. Ramani, N. S. ChaudhariIntranet often employ an Internet firewall to mitigate risks of system penetration, data theft, data destruction and other security breaches. Conventional Internet firewalls impose an overly simple inside vs. outside model of security that is incompatible with many business practices that require extending limited trust to external entities. Additionally, firewall security perimeters are somewhat weak: they provide no protection from … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,710 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Environmental Decision Support System Based on a Multidimensional PrototypeGeorgakellos Dimitrios, Macris AristomenisThe present study utilizes the principles and data provided by the Environmental Priority Strategies (EPS) methodology in order to create a multidimensional prototype, which intends to assist the damage assessment process in this kind of projects. The EPS system, based on Life Cycle Assessment (LCA) methodology, is developed to help designers and product developers in finding which one of two … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,624 accessesView PDFCite
Research ArticleOpen accessIn the abstractIncreased Production of Nitric Oxide Contributes to Renal Oxidative Stress in Endotoxemic RatBahar Tunçtan, Belma Korkmaz, Hatice Yıldırım et al.Overproduction of reactive oxygen and nitrogen species leads to oxidative stress and decreased total antioxidant capacity, which is responsible for high mortality from several diseases such as endotoxic shock. Nitric oxide (NO) produced by inducible NO synthase (iNOS) during endotoxemia is the major cause of vascular hyporeactivity, hypotension and multiple organ failure. In this study, we investigated whether increased production … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 8,643 accessesView PDFCite
Research ArticleOpen accessIn the abstractERCP Related SepsisIffet Palabıyıkoglu, Emin Tekelı, Derya Aysev et al.Endoscopic procedures performed worldwide have increased considerably in recent years. In addition to diagnosis, many cases previously necessitating surgery now often can be carried out by endoscopic techniques. However, endoscopy has introduced its own infection risk. Most reports of gastrointestinal endoscopy-associated infection describe sepsis after endoscopic retrograde cholangiopancreatography (ERCP) in patients with biliary tract obstruction. During this study, which was … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 7,024 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Probability Curves Obtained from 2 Quantitative Allergen-specific IgE Assays: FEIA and 3gAllergyTMT. M. Li, T. Chuang, S. M. Li, D. Hovanec-BurnsThe validity and benefit of probability curves in allergen-specific IgE (sIgE) testing and their applicability to more than a few allergens are still pending. One study[1] presented probability curves for 4 food allergens and proposed decision points to rule out the need for food challenges in his clinic. Since then, such cutoffs were reported by Boyano-Martinez[2] to be dependent on … …American Journal of Immunology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,740 accessesView PDFCite
Research ArticleOpen accessIn the abstractContribution of Advective and Non-advective Heat Fluxes to the Heat Budget of a Shallow LagoonRodríguez-Rodríguez MiguelThe heat budget in a shallow lagoon has been established from field measurements at a bihourly scale. Information on the main advective and non-advective heat fluxes were collected during year 2003 at Nueva lagoon (Almería, Southern Spain). Heat storage data was obtained from a thermistor chain located in the deepest part of the lagoon and meteorological information was acquired using … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,495 accessesView PDFCite
Research ArticleOpen accessIn the abstractValidation of Some Bridge Pier Scour Formulae Using Field and Laboratory DataThamer A. Mohamed, Megat J.M.M. Noor, Abdul H. Ghazali, Bujang B.K. HuatEstimation of maximum local scour depth at the bride pier site is necessary for the safety and economy of the designed bridge. Numerous formulae are available and almost all of these formulae were developed based on laboratory data. Validation of these formulae is necessary in order to ascertain which of the formulae will give a reasonable estimate of the local … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 7,829 accessesView PDFCite
